PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 242,664, dated June 7,1881. Application filed March is, 1881. (ModeL) To all whom it mayconcern Be it known that I, CHARLES A. S. LooK- W001), of Haverstraw,Itockland county, New York, have invented a new and useful Improvementin Paper Bags, of which the following is a specification.

Figure 1 is a plan view of a blank for one of my improved bags ready forfolding. Fig. 2 represents the bag with the bottom nearly formed, andFig. 3 represents the bag with the bottom fully formed.

Similar letters of reference indicate corre sponding parts.

The object of this invention is to facilitate the manufacture of paperbags and economize the use of stock in their construction.

In making my improved bags the paper is out into rectangular shape andof such dimensions as will form bags of the required size. To the loweredge of the blank A is pasted or upon it is formed a rectangular piece,B, to form the bottom of the bag. The blank A is then folded so that theside edges will overlap, andthe said overlapped edges are pastedtogether. The part 0 of the lower edge to which the flap B is attachedand the part D, opposite the said flap, are folded down toward eachother in triangular form, bringing the flap B beneath the edges of thesaid parts 0 D, leaving a space between their edges. The end parts, E F,of the flaps formed by making the folds G D are then folded down, sothat their edges will overlap the bottom B, leaving a space betweentheir edges, as shown in Figs. 2 and 3.

In making the bags each fold is pasted down so as to form a closebottom, with no open scams or pockets for the substance put in the bagto get into. In the case of large bags a second piece or flap, B, can beattached to the lower edge of the blank'A in such a position as to bedirectly opposite the flap B when the side edges of the said blank arefolded together,

so that when the formation of the bag-bottom is completed one of theflaps B will be upon the inner side of the bag-bottom, and the otherupon the outer side of the said bottom.

By this construction strong and reliable bags are produced, and a savingof fully one-tenth of the stock is effected over the ordinaryconstruction.

Having thus described my inven tiou, I claim as new and desire to secureby Letters Patent- A paper bag having a central flap, B, with the foldsOD E Farranged thereupon, as shown and described.
